Abstract: A flush-mounted plug connector is suitable for use in a battery management system. A plug connector housing has an assembly flange for assembling the plug on a housing wall of a housing, e.g. of the battery management system. A plug contact is integrated into the plug connector housing. The plug contact has a plug-in axis, a plug-in region, and a cable connection region. The cable connection region can be connected to the battery management system via a connection cable which is designed as a high-current cable. The cable connection region is designed as a crimp connection such that the plug contact is a crimp contact which is held in the plug connector housing in a rotatable manner about the plug-in axis at least during the assembly process, and after being assembled, the integrated crimp contact can be disassembled again by means of a disassembly tool.

Abstract: A modular system for plug connector modules for producing plug connector units, and to at least one first housing frame for receiving a plurality of plug connector modules within the housing frame. Each housing frame has two parallel longitudinal side walls, which define the frame width of the housing frame, and perpendicularly thereto two parallel narrow side walls, which define the frame height of the housing frame. According to the invention: i) the frame width is an integer multiple of the frame height, optionally plus joint play; ii) the longitudinal side walls and the narrow side walls have connection elements for form-fitting connection, wherein in each case a connection element of a longitudinal side wall corresponds to a connection element of a narrow side wall; and iii) on each longitudinal side wall a plurality of connection elements are arranged at a grid distance which corresponds to the frame height, optionally plus joint play, along the frame width.

Abstract: A locking clip for plug housings has a rear wall and side parts formed on the rear wall. The locking clip has a U-shaped cross-section. The side parts each have a mounting receptacle, by which the locking device can be pivotably mounted on the plug housing. The locking device has an embossment directed toward the plug housing in the region of each mounting receptacle. Thus, the locking device is not supported on the plug body over the full surface, and therefore a lower-wear locking operation is ensured. A system includes a first plug housing and a second plug housing and a locking clip. The locking clip is pivotably mounted on the first plug housing by mounting pins. The locking clip can be locked on the second plug housing on locking pins. The locking clip touches the plug housings only at the mounting pins and at the locking pins.

Abstract: Disclosed is a connector assembly having a first connector part and a second connector part. The first connector part includes a lever mounted on a base body of the first connector part for pivotable movement about a pivot axis (C) between first and second positions relative to the base body. The connector assembly can be brought from a ready-to-mate state into a mated state by relative movement of the first and second connector parts towards each other along a connection axis and vice versa. At least one engaging portion of the lever interacts with at least one counter-engaging portion of the second connector part in such a way, that the connector assembly is forcibly brought from the mated to the ready-to-mate state by pivoting the lever from the first position into the second position when the connector assembly is in the mated state.

Abstract: The disclosure relates to a protective cap for an attachment housing. The protective cap has a basic shape which is substantially box-shaped. The protective cap has a first locking device on the narrow faces of the box-shaped basic shape, and the protective cap has a second locking device on at least one broad face of the box-shaped basic shape. The disclosure likewise relates to a system comprising such a protective cap and a matching attachment housing. Advantageously, the locking devices of the protective cap can be used with and without a locking bracket of an attachment housing.

Abstract: A latching mechanism for plug contacts in insulating housings of plug connectors is provided. The latching mechanism which, in addition to the known arrangement of a latching arm and latching shoulder, provides a latching lug on the latching shoulder. As a result of the latching lug, the latching mechanism is prevented from becoming released under a mechanical load. The latching lug enables additional latching of the latching arm against the plug contact.
